In physics, the elements in a circuit could involve a resistor-capacitor, resistor-inductor, or just solely their own type of circuit. For a resistor-capacitor or RC circuit, the potential difference or voltage induced between the parallel plates of a capacitor is related by this equation:
Q = C × V, where
Q is charge in Coulombs C is the capacitance in Faradays V is the voltage in volts
I think the correct answer from the choices listed above is option D. One advantage of using electromagnets in devices would be that electromagnets can <span>easily be turned on and off. Hope this answers the question. Have a nice day.</span>
